MACHINE FOR OPERATING UPON SOLES.

Specification of Letters Patent.

Patented June 25, 1912.

Application filed March 2 4, 1909. Serial No. 485,486. i

To all whom it may concern:

Be it known that I, FREDERIG E. BER- TRAND, a citizen of the UnitedStates, residing at Swampscott, in the county of Essex and State ofMassachusetts, have invented certain new and useful Improvements inMachines for Operating upon Soles; and I do hereby declare the followingto be a full, clear, and exact description-of the invention,

such as will enable, others skilled in the art towhich it appertains tomake and use the same. r

. This invention relates to machines for operating on the soles ofboots. and shoes known in the-art, broadly, as channeling machines, andmore particularly to such machines for preparing soles to .beincorporated into turn shoes, or in preparing insoles for womenswork.

In both welt and turn work a channel cpt n welt work the edge of thesole is also slit, in addition to the channel cut in the sole face, thelip thus formed being turned up to form a shoulder against which theupper is lasted and the welt is sewed. In turn work no lip is formed atthe edge of the sole, the upper portion of the margin of the sole beingentirely removed to form a shoulder,-or striking surface, for the pointof the needle. Insoles for womens workare also prepared in this way. I

The same form of shoulder cut in the sole is not desirable in all kindsor styles of shoes, for instance, in cases where an extreme feather edgeis desired the feather will be beveled sharply outward from'the base ofthe shoulder, while in cases where it is desired to preserve thethickness of'the sole at its outer edge the direction of bevel isreversed sloping from the outer edge of the sole inward to the base ofthe shoulder. Frequently it is desirable to cut a simple rabbet in themargin of the sole leaving the surface of the feather parallel to thesurface of the sole. In order to .be able to change the form of theshoulder cut, and

thus render a machine capable of accorrimodifferent shoulder cutsreferred to the knife assumes a different vertical position relative tothe surface of the work. support therebynecessitating a differentverticalpoj sition of the knife block each timethe form' of the knife ischanged. Heretofore, when the knife has been changed. to obtaindifferent forms of shoulder out, it hasbeen necessary to readjust theknife block-onits' car rier in order to place the knife in such verticalrelation to the work support that it will properly perform its work.This fre-' quent adjustment is undesirable because of the waste of timeentailed, and the loss of time is enerally considerable because themeans wiereby the adjustment of the knife block is effected isofteninconveniently. located and therefore not readily accessible.

With these considerations in view, the object of the. present inventionis to provide a shoulder knife block, which is readily re-J movable,with means for instantly locating it on its carrier with the knife whichit holds, of whatever form it may be, in the a vertically adjustablemember having a portion adapted to fit in such recess, for instance, aheaded screw' threaded into the knife block, thus forming a tongue andgroove connection between the parts. If the head of the scr w ispreliminarily adjusted so that when pl aced in the recess the knife willassume the desired position, it will then be necessary merely to clampthe knife block to its carrier, andthe machine is ready to commenceoperations without any'ad ustmentof the knife whatever after it is inthe machine.

It is'customary to have at the machine a number. of knives of differentform ready for use when desired and the present inventioncontemplatest-he use of a number of knife blocks, each having itsspecial form of knife clamped therein in proper relation to the edgegage for the Width of feather, and

. parts,.are the same as illustrated and de-.

each having an adjustable member, as debe provided for locking the saidmember in 2 its adjusted position so that this position cannot bedisturbed.

To gain this end the preferred form of e the present inventioncontemplates 'a spliteared lug on the knife block, into which the headedscrew is threaded, and a clamping screw for tightening the split earsafter the desired location of the screw in the lug. has been determined.

The invention comprises the features and combinations of partshereinafter described and particularly pointed out in the appendedclaims. i The preferred embodiment of the invention is illustrated inthe accompanying draw- .ings, in which Figure l is a rear elevation of asole channeling machine having the presentinvention incorporatedtherein; ig. 2 is an elevation of the knife holder shown in detail, theknife holder being provided with one form of shoulder knife; Fig :3 is aplan of the parts shown in Fig. 2, the knife block carrier being shownin section; and Fig.4 is a view similar to Fig. 2 but illustratingtheinvention in use with a different form of shoulder knife.

Referring to the drawings and more particularly to Fig. l, H designatesgenerally the head of a sole channeling machine of the type illustratedin Letters Patent of Great Britain to Alfred J. Boult, No. 13,052, datedJune 18, 1908, with the chamfer knife and the channel knife raisingdevices removed. .The channeling knife, work feeding and positioningdevices, their actuating mechanisms and other cotiperating scribed indetail in said British Letters Patent. These portions of a channelingmachine,'as illustrated in Fig. 1, are shown by way of example only asthe present invention is not limited in its application to anyparticular type of channeling machine. As in the machine of said BritishLetters Patcut, and for the purpose therein explained, the channel knifewith its presser foot, and the edge knife with its presser foot, aremounted on carriers comprising independent, yieldingly mounted lidessuitably supported in the machine frame. f

Referring now more particularly to Figs. 2 to 4, 2 designates thecarrier slide which supports at its lower end the edge knife block 4cand the edge presser foot 6 The presser foot is adjustably and removablymounted on a presser foot block 8 by means of a tongue and grooveconnection (Fig. 3) and a clamping screw .10 passed through 2.

slot in'one of the'parts. The presser foot block is mounted for movementtoward and from the work to accommodate varying 5 thicknesses of stock,in a toe 12 on the knife j block carrier 2, by means of a verticaldovetail tongue and groove connection (Fig. 3). A wear plate is held inplace by means of set screws l4.' The presser foot is held yieldingly inengagement .with the work by 1 means of a grasshopper spring 13 havingone end inserted in the prcsser foot block and its other end held in alug 15 on the frame in which the slide 2. moves.

The knife block 4 is provided with a vertical tongue (Fig. which fitsina vertical groove in itscarrier 2. The knife block is held to itscarrier'by means of a collared screw 18 which passes through a verticalslot 20 in theknife block and bears with its head upon a horse-shoewasher 22. The collar ofthe screw 18 is of such diameter, relatively tothe width of the slot 20, that, on loosening the screw and slipping offthe washer, the knife block can be removed from its carrier withoutentirely removing the screw. and washer are readily accessible (seeFig. 1) and the knife block can be easily and quickly removed. Theshoulder knife 24is adjustahly held in a recess, formed for itsreception in the knife block, by a set screw 26. The rear end of theknife block is provided with a split lug 28 into which there is threadedvertically a screw having a milled head-30. The split ends of the lug 28may be drawn together, and the screwheld securely in any desiredposition of adj ust-ment,

face of the knife block-slide 2 is provided with a horizontal groove 34(dotted lines Figs. 2 to 4) of sufficient depth to receive the screwhead 30. The screw head 30 and groove 34 form a tongue and grooveconnection of which one element is adjustable on the part which carriesit.

Fig. 2 illustrates a shoulder knife for forming a cut which preservesthe thickness of the sole at its edge, and Fig. 4 illustrates ashoulder; knife which forms a feather edge on the sole. An inspection ofthese figures shows that the vertical relation of the knife to thesurface of the work whereby the distance of the knife above the worktable, when in operating position, may be correctly-determined, for allforms of knives. When a machine is first set up a shoulder knife blockis provided for each form of shoulderknife it is desired to use in themachine. These are successively rier 2 with the screw head 30 in thegroove 3%. In each ease the'knife is adjusted for width of feather andthen secured in place With this construction the screw table 36isdiflerent in each case. The screw'having the head 30 forms a device bymeans of a clamping screw 32. The rear placed, as desired, on the knifeblock carby the screw 26, and also for the height of the particularknife in the block above the work support by an adjustment of the screwwhile its head 30 remains in the groove 34, the screws 18 and 32 at thistime being loosened. After this latter adjustment is made the adjustingscrew in each case is locked in its adjusted position by the clampingscrew 32. After each knife has been adjusted in its block for theparticular cut it is to make they are placed beside the machine and itis obvious that any knife of the series can instantly be mounted incorrect working position, without an additional adjustment whatever, bysirnp placing the screw head 30 in the groove in the knife block carrierand then securing the knife block in the position thus determined bytighteningits clamping screw 18. This is true because the clampingiscrew32; holds the adjusting screw invariably in its adjusted position and,therefore, the knife must, of necessity, assume its correct workingposition when the screw head 30 and groove 34 are placed in enga ement.

While the particulars 0 construction herein set forth are well suited toone form of the invention, it is not tobe understood that theseparticulars are essential since the i may be variously modified withinthe ski of the artisan without departing from the true sco e of theactual invention as defined by the f bllowing claims.

What is claimed as new, is 1', A machine for operating upon soles,having, in combination, a knife blockcar- &

rier, a knife block removably mounted there on, a headed screw threadedinto one of said parts, the other of said parts having a groove, thescrew head and groove being adapted to engage each other when the knifeblock is in workin position on its carrier, and means for loc ring thescrew in any desired position 0t adjustment whereby a proper replacementafter a temporary separation .is insured, substantially as de scribed.

' 2. A machine for operating upon soles,

having, in combination, a knife block carrier having a horizontalgroove, a knife block,

a screw threaded vertically into the knife.

locking the adjustable element in any desired position of adjustment,substantially as described.

In testimony whereof I alfix my signature,

in presence of two witnesses.
